Cut tofu block into 6 equal sized cubes, and shave off extra as needed (save scraps). Flip each cube on its side. Carve out the middle of each cube with a spoon a little more than half way deep (save scraps as well). Set cubes aside. Throw all scraps and remaining ingredients into a food processor. Add water as needed to achieve desired consistency. Process thoroughly and place in a pastry bag. Squirt contents into your hollow out tofu blocks and tell your guests they are square eggs garnish with black pepper and enjoy!
